RIDGE CAI.

Application filed January 15, 1927. Serial No. 161,417.

This invention relates to ridge caps or rolls such as are used on roofsapplied to the hips and ridges thereof.

The general object of the present invention is to provide a ridge cap ofa very simple form but which will absolutely prevent hard beating rainfrom being blown up over the end of the roofing sheets.

A further object is to provide a ridge cap of such construction that thenails will be entirely covered up and protected and which will beleak-proof.

My invention is illustrated in the accompanying drawings wherein Figure1 is a vertical sectional view of a roof having my ridge cap appliedthereto;

Fig. 2 is a perspective view of the ridge eferring to these drawings 10designates the sheathing of a roof and 11 the ridge cap or rollgenerally. This comprises the medially disposed enlarged bead 12 and thelateral wings 13. Each of these wings along its margin is bent downward,as at 14, so as to provide a downwardly extending flange and inward ofthis flange the margin of the roll or cap is bent upward, as at 15, thenrearward and downward, as at 16, and then returned upon itself, as at17, and extended beyond the flange 14. The roofing sheets 18 are formedeach at its upper margin with an upwardly turned flange 19 which isadapted to hook beneath the flange formed by the portions 14 and 15. Inthe use of this device, the ridge roll is placed in position and theportion 17 nailed to the sheathing by the nails 20. Theroofing sheetsare then turned upward so as to insert the flange 19 beneath the flange14 and then the roofing sheet is turned downward over the sheathing andnailed thereto or otherwise engaged therewith in the usual and ordinarymanner.

It will be seen that the roofing sheet is anchored along its uppermargin to the 5 flanges 14 and of the ca or roll and that the flange 19is of such height that water cannot be blown in a hard driving rainbeneath the flange 14 and up over the flange 19 so that a leak-proofconnection is formed between the ridge roll and the root'- ing sheet andfurther it will be seen that the nails 20 which hold the roofing sheet-In place are entirely protected. Even if a hard wind tended to oractually did raise the wing 13, the water would then be arrested by theflange 19 so that even under the worst circumstance there is nopossiblity of the roof leaking at this point.

It will be seen that this ridge cap or roll is relatively simple. thatit may be cheaply made, and is thoroughly efl'ective in actual practice.

I claim 1. A ridge roll having downwardly and outwardly extending wings,each wing at its margin being formed to provide a downwardly extendingflange, the material of the roll being bent upward inside the flange andthen rearwardly and downwardly and forwardly beyond the flange toprovide a nailing portion.

2. A ridge roll having downwardly and outwardly extending wings, eachwing at its margin being formed to provide a downwardly extendingflange, the material of the roll being bent upward inside the flange andthen rearwardly and downwardly and forwardly beyond the flange toprovide a nailing portion, in combination with a roofing sheet havingits upper margin transversely flanged to engage behind the flange of theroll and over the nailing portion of the roof.

3. In a roof, a roofing sheet having an upwardly extending flange at itsupper man gin and a ridge roll having a downwardly extending wing formedat its margin with a flange engaging over said flange on the roofingsheet, the ridge roll beyond this flange being extended upward andrearward behind the flange of the roofing sheet and then downwardbeneath the roofing sheet.

In testimony whereof I hereunto aflix my signature.

OLIVER P. GREENSTREET.
